System for monitoring the status of rotor blades on wind energy facilities

摘要

The system has a sensor (1) that is provided at sensor nodes (S1,S2) for spatially resolved detection of vibrations or acoustic waves of rotor blades. The sensor nodes are connected with a central supplying and receiving unit (4) by optical fibers (2,3). A light source (4.1) is connected at the central supplying and receiving unit, from which electromagnetic radiation is guided by the optical fiber to a photovoltaic converter (5).
